- which the following is a specification.

ism for controlling said valve, together with the flushing-valve.

The precise construction of the parts above named is pointed out in thefollowing specification and illustrated in the accompanying drawings, inwhich Figure 1 represents a side view, partly in.

section. Fig. 2 is a longitudinal vertical sec tion in the plane .19 a,Fig. Fig. 3 is a trans verse vertical section in the plane yy, Fig. 2.Fig. 4 is a detached elevation of the lifting-rod.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the bowl of a water-closet,which may be constructed of earthenware or of any other materialsuitable for the purpose, and which is provided with a discharge-valve,B, in one side, near its bottom, while it connects at the opposite side,near its top, with the flushing-pipe O. O is the overflow-pipe. Thevalve B is secured to a rock-shaft, D, which has its bearings in thesides of the valve-chamber E, and extends through one side thereof asufiicient distance to make room for a lever, F. The outer end of thislever extends through a slot, (1, in the lifting-rod G, (see Fig. 4,)andis provided with a weight, I), which has a. tendency to keep the valve Bclosed.

The flushing-pipe Ccommunicates with the water-supply pipe H by a valve,I, which may be termed the flushing-valve, and which is situated in thevalvechamber J and closes up against its seat c by the action of theweighted lever K. This lever has its fulcrum on a pivot, 11, and itconnects at one end with the stem c of the flushing-valve I, while itsopposite end extends through a slot, f, in the lifting-rod, and isprovided with a weight, 9. Between its pivot d and weight g the lever Kis connected rod is raised by its handle 7; the discharge' valve B ofthe bowl and tl'ie'flushing-valve I are opened and the matter containedin the pan is washed out, while at the same time the air-cushioningpiston L is raised up in the cyl inder M. \Vhen the lifting-rod ispermitted to drop the discharge-valve B is immediately closed by thecombined action of the weight b on the lever F and the weight 7' on theliftingrod; but the flushing-valve I remains open for a short time afterthe discharge valve has closed, because the lever K is supported by theair-cushioning piston L, and the slot f in tlie lifting-rod is of such alength that the weight j of said lifting-rod does not bear upon thelever K. The air-cushioning piston is slowly depressed by the weight gof the lever K, while the air from the lower portion of the cylinder Mescapes through the opening or openings '1'. During this period of timethe flusl'iing-valve I remains open, and the required quantity of waterflows into the pan before said valve closes.

The valvechamber E, which contains the discharge-valve B, is providedwith a bottom flange, I, which is secured to the flange m of thesiphon-trap I by screws 91. In the interior of the valve-chamber isformed a recess, 0, to receive a surrounding flange on the valve seat Q,which is fastened by screws (1 passing through its flange. Between theinner surface of this flange and the breast of the pan is formed aputty'joint, r. The rear portion of the pan rests upon a cup-shapedsupport, S, which is fastened to ears 8 on the siphon-trap I, while thefront portion of said bowl is provided with downwa (Hy-projecting flanget, which rests upon the flange l of the valve chamber. On thesiphon-trap P is formed a shoulder, a, and between this shoulder and theflange t is inserted a wedge, T, by preference of wood. By driving thiswedge in, the breast of the bowl is drawn up tight against the face ofthe valve-chamber, the putty joint 1 serving to prevent leakage. Bythesemeans the bowl can be very readily adjusted in position, and it can alsobe readily removed whenever it becomes desirable.

The dischargevalve B is constructed of two disks, 0 and w, the diskvbeing firmly mounted on the rock-shaft D, while the disk w is connectedto the disk 11 by a screw, a, passing through its center. On its innersurface said disk w is provided with a rim, 2/, and with an annular rib,e, and inside of this annular rib is placed a gasket, (1, of elasticrubber or other equivalent mz'tterial. By tightening up the screw (1 thegasket (1 is compressed to such an extent that the disk is firmlyretained in position; but I do not screw up the screw (1 suificientlvtight to cause the rim I) of the disk In to bear firmly all aroundagainst the inner surface of the disk 1*, so that in closing the valve Bthe disk :0 can yield and accommodate itself to the valve-seat Q, theweightj on the lifting-rod and weight I) on the lever F acting upon thevalve B with. sufficient pressure to produce the desired effect.

\Vhat I claim, and desire to secure by Letters Patent, is

1. In a water-closet, the combination of the siphon-trap P, providedwith the flange m and lateral earss, the cup shaped saddle S, detachablyconnected with the ears of the siphon-trap, the valvcchamber E, having abottom flange, detachably connected with the flange of the trap, and thebowl A, joined at its breast end to the "alvcchamber, and at its otherend rcstiiig in the cup-shaped saddle, substantially as described.

2. The combination of the siphon-trap l? and valve-chamber E, detachablyconnected together, and the trap having a shou1der, w, with the bowl A,provided with a flange, 2, a putty joint, r, at the breast of the bowl,and a Wedge, T,,arranged between the shoulder on the trap and the flangeon the bowl, substantially as and for the purpose described.

' 3. The combination, with the bowl A, valve chamber E, and valve-seatQ, all detachably united, of the shaft D, extending through thevalve-chamber, the valve B, hung on said shaft and composed of two disksand an interposed elastic gasket, the inner disk resting 011 thevalve-seat, the weighted lever F, attached to the shaft of the valveoutside the valve-chamber, and the lifting-rod G, connected with thelever, substantially as described.

at. The combination, substantially as herein described, of the pan A,the valve-chamber E, containing the discharge-valve B, the rockshaft D,the lever F, extending through a slot in the lifting-rod G, theflushing-valve I, the air-cushioning piston L, and the lever K,connected to the flushing-valve and to the aircushioning cylinder andextending through a long slot in the lifting rod and the flushing pipe.

In testimony whereof I have hereunto set my hand'and seal in thepresence of two subscribing witnesses.
